Abstract
Bekannt ist eine Sensoreinrichtung mit einem Sensor zum optischen Erfassen von Fremdkörpern, insbesondere Regentropfen, auf einer Scheibe (1) mit einem Sensorelement, insbesondere einem Lichtleiter (5), der über ein Koppelelement (3) an die Scheibe gekoppelt ist, welches Koppelelement eine regelmäßige 3-D-Oberflächenstruktur (7) aufweist. Erfindungsgemäß ist vorgesehen, dass die 3-D-Oberflächenstruktur (7) des Koppelelementes scheibenseitig ausgebildet ist, und dass die Scheibe (1) koppelelementseitig glatt ausgebildet ist.Known is a sensor device with a sensor for optically detecting foreign bodies, in particular raindrops, on a pane (1) with a sensor element, in particular an optical fiber (5), which is coupled to the pane via a coupling element (3), which coupling element is a regular one 3-D surface structure (7). According to the invention, the 3-D surface structure (7) of the coupling element is designed on the disc side and the disc (1) is smooth on the coupling element side.
Description
Die vorliegende Erfindung betrifft eine Sensoreinrichtung, insbesondere einen Regensensor, gemäß dem Oberbegriff des Patentanspruches 1 sowie ein entsprechendes Montageverfahren.The present invention relates to a sensor device, in particular a rain sensor, according to the preamble of claim 1 and a corresponding assembly method.
Eine derartige Sensoreinrichtung
ist bekannt aus der
Bekannt ist weiterhin aus der
Aus der
Bekannt ist also allgemein, dass Regensensoren an die Scheibe angekoppelt werden. Das Koppelmedium besitzt dabei entweder Ballonform und wird durch Druck an die Scheibe gepresst oder das Koppelmedium – ein beidseitig glattes Klebeband – wird unter Unterdruck an die Scheibe geklebt. Beides geschieht zur Vermeidung von im optischen System und unter Designgesichtspunkten störenden Luftblasen.So it is generally known that Rain sensors are coupled to the window. The coupling medium has either a balloon shape and is pressed against the pane pressed or the coupling medium - a double-sided smooth adhesive tape - will glued to the pane under negative pressure. Both are done to avoid of air bubbles that interfere in the optical system and from a design point of view.
Erfindungsgemäß ist eine Sensoreinrichtung mit den Merkmalen des Patentanspruches 1 und ein Montageverfahren nach Patentanspruch 7 bereitgestellt. Ein Vorteil der Sensoreinrichtung besteht darin, dass die Luftblasen kontrolliert in Bereichen entstehen, die für die Funktion zumindest weniger kritisch sind, z.B. außerhalb des optischen Weges bei groben Strukturen bzw. bei feinen Lichtwegen. Zudem wird durch die definierte Position und Form der Lufteinschlüsse eine für das Design akzeptable Anmutung erzeugt. Erfindungsgemäß kann darauf verzichtet werden, eine 3-D-Oberflächenstruktur aufwendig in der Scheibe zu erzeugen.According to the invention, a sensor device is provided with the features of claim 1 and an assembly method Claim 7 provided. An advantage of the sensor device is that the air bubbles are created in controlled areas the for the function is at least less critical, e.g. outside the optical path for coarse structures or fine light paths. In addition, due to the defined position and shape of the air pockets for the Design creates an acceptable impression. According to the invention be dispensed with, a 3-D surface structure complex in the Generate disc.
Vorteilhafter Weise kann eine Strukturgröße der 3-D-Oberflächenstruktur etwa 10–2 bis 10–6 m, insbesondere 10–3 bis 10–5 m betragen. Bei zu großen Strukturgrößen kann es zu ungewollten Luftblasen an der Grenzfläche zwischen dem Koppelmedium und der Scheibe kommen. Bei zu kleinen Strukturgrößen kommt diese in die Größenordnung der Rauhigkeit der Scheibe, wodurch eine undefinierte Ankoppelfläche gebildet wird.A structure size of the 3-D surface structure can advantageously be approximately 10 -2 to 10 -6 m, in particular 10 -3 to 10 -5 m. If the structure sizes are too large, unwanted air bubbles can occur at the interface between the coupling medium and the disk. If the structure sizes are too small, this comes into the order of magnitude of the roughness of the disk, as a result of which an undefined coupling surface is formed.
Um eine ausreichende Stabilität der Struktur sicherstellen zu können, ist vorgesehen, dass ein Verhältnis von Breite zu Höhe der Erhöhungen der 3-D-Oberflächenstruktur etwa 3 bis 20, insbesondere um 10 beträgt.To ensure adequate stability of the structure to be able there is a relationship from width to height of increases the 3-D surface structure is about 3 to 20, especially around 10.
Durch das erfindungsgemäße Montageverfahren können die hohen Kosten und der komplizierte Montageprozess mit der Unterdruckklebung bzw. der aufwendige Aufbau mit Federkonstruktion und Halteplatte deutlich vereinfacht oder vermieden werden; es ist eine einfach zu handhabende, kostengünstige und schnelle Alternative der Befestigung der Sensoreinrichtung bereitgestellt. Die Montage des Koppelmediums kann zunächst blasenfrei am Lichtleiter erfolgen und entsprechendes gilt aufgrund der 3-D-Oberflächenstruktur für die nachfolgende Montage des Koppelmediums an der Scheibe. Dadurch ist erstmals eine Montage der Sensoreinrichtung im Fahrzeug möglich.Through the assembly method according to the invention can the high costs and the complicated assembly process with vacuum bonding or the complex structure with spring construction and holding plate be significantly simplified or avoided; it's an easy one manageable, inexpensive and quick alternative of attaching the sensor device provided. The coupling medium can initially be installed on the light guide without bubbles due to the 3-D surface structure for the Subsequent assembly of the coupling medium on the disc. This is the first time the sensor device can be installed in the vehicle.
Gemäß einer bevorzugten Ausführungsform kann die Befestigung des Sensorelementes an der Scheibe bei Unterdruck erfolgen. Erfindungsgemäß wird die Luft aus den Vertiefungen der 3-D-Struktur entfernt und es kommt zu einer im wesentlichen vollständigen Ankopplung des Lichtleiters an die Scheibe. Vorteilhaft ist insbesondere, dass vergleichsweise geringe Drücke zur Realisierung der Blasenfreiheit erforderlich sind bzw. größere Flächen des Koppelelementes blasenfrei angeklebt werden können.According to a preferred embodiment, can the attachment of the sensor element to the disc at negative pressure respectively. According to the Air is removed from the recesses in the 3-D structure and one is formed essentially complete Coupling the light guide to the pane. It is particularly advantageous that comparatively low pressures are necessary to achieve freedom from bubbles or larger areas of the Coupling element can be glued bubble-free.
Nachfolgend sind ein Ausführungsbeispiel der erfindungsgemäßen Sensoreinrichtung und das Montageverfahren beschrieben; es zeigt die einzige Fig. stark schematisiert die montierte Sensoreinrichtung.Below is an embodiment of the sensor device according to the invention and described the assembly process; it shows the only fig. the sensor device is highly schematized.
